May be old news to some, but I had to re-warp some shelves in the bathroom closet the other day, and found a small, old, dusty brush in the corner. It had a handle about 3" long and very fine nylon bristles shaped sorta like a boat tail bullet. I've been cleaning small parts and holes with it (does a great job) When my wife saw it, she says, "look at me". I did, and asked her why. She said she wanted to know what I was doing with her mascara (sp) brush. She just ordered some make-up stuff and I had her get several of those brushes for me. I always knew cosmetics were good for something. :t
